Scudder.] 92 [November 6, 
the surface scarcely scabrous; beneath the whole forms a short, 
conical, depending process, separated from the conically produced 
front by a pretty wide frontal incisure. Pronotum short, subseabrous, 
the posterior somewhat more than twice as long as the anterior lobe, 
the median incisure open U-shaped, the posterior lobe rapidly ex- 
panding on its basal two-thirds, the lateral carine distinct on the 
posterior half of the whole pronotum ; posterior edge nearly straight. 
Tegmina pretty slender, rather regularly rounded at the extremity, 
the tip scarcely produced and slightly below the middle. Fore and 
middle femora with two or three pretty stout spines on the apical 
half of the lower outer carina; hind femora moderately stout, furnished 
beneath with rather distant, pretty stout spines, excepting next the 
base; hind legs rather short, the tibie two thirds as long as the 
tegmina. Last dorsal segment of the ¢ abdomen produced as in C. 
malivolans, but much more briefly and neither arched nor apically 
compressed; supraanal plate moderate, triangular, depressed toward 
the middle so as to be canaliculate, the sides roundly excised, the 
apex pointed; upper tooth of anal cerci forming an inward directed, 
recurved and slightly downward trending, pointed hook; lower tooth 
long and slender, appressed, conical, in- and recurved, rather bluntly 
pointed, with a continuous apical spine; styles slender, cylindrico- 
conical, as long as the lower tooth of the anal cerci; ovipositor (in 
the pupa) considerably longer than the hind tibie. 
Length of body, 27 mm.; of fastigium beyond the front edge of 
the eyes, 2 mm.; of pronotum, 7.5 mm.; of tegmina, 34 mm.; of hind 
tibia, 21.5 mm. 8 2, besides 1 ¢, 2 2, (pupe). Mexico, April, 
Sumichrast. 
This seems to be distinct from any of the species which have been 
described from Mexico by Saussure and Walker. 
98. Conocephalus hebes. A large but not very stout 
species, green or brown; and when the latter, the upper edge of the 
deflected lobes of the pronotum and of the anal area of the tegmina 
marked with a slender, blackish brown stripe, which continues to and 
around the fastigium; the front of the fastigium is also marked with 
black in the green specimens; and sometimes the tegmina, in the 
brown variety, are flecked irregularly and infrequently with black 
dots near the middle line. Fastigium stout, short, subequal beyond 
the narrowing base, broadly rounded at tip, extending scarcely fur- 
ther beyond the front edge of the base of the eyes than the width 
between the eyes, not more than one-fourth longer than the median
